1. An Analog Front End (AFE) channel driver circuit comprising:
a differential module configured to process a channel driving signal and a reference signal to generate an analog error signal, wherein the channel driving signal is provided to an interface of the AFE channel driver circuit; and
a driver module operably coupled to the differential module and configured to:
process the analog error signal to generate the channel driving signal; and
transmit the channel driving signal to the interface of the AFE channel driver circuit, wherein the differential module and the driver module are configured to operate cooperatively to transmit the channel driving signal to the interface of the AFE channel driver circuit via a single line and simultaneously to sense the channel driving signal that is provided to the interface of the AFE channel driver circuit via the single line.
